Idris Rafiq Muhammad, 20, and Khalifah Muhammad, 18, died last night on Layhill Road, near Middlevale Road in Silver Spring. Their 2006 Nissan Senta hit the right-side curb, left the roadway and hit a utility pole.

The older brother had been driving. Police say both were wearing their seatbelts at the time.

The two women in the back seat, ages 17 and 18, were not wearing their seatbelts. They were injured, but both are expected to survive.
